A PCI-minded questionnaire for city payments Wi-Fi asks whether TKIP is an acceptable cipher. What is the correct answer?
Select an answer to reveal the explanation.
Short Explanation
For payments Wi-Fi, TKIP is a hard no. Modern suites expect AES/CCMP-class crypto; a captive portal page, a locked closet, or paperwork does not rehabilitate TKIP.
Full Explanation
TKIP is listed among modern insecure technologies that should not be used. Payment-adjacent or PCI-minded municipal WLANs still require contemporary cipher selection—typically AES/CCMP under WPA2/WPA3—not TKIP justified by captive portals, physical PoE placement, or undocumented compensating language.
